Any help appreciated.

Thanks

4. That minus sign on your last step is a trouble maker, as that will get you nowhere really.

from your 4th step its straight forward from there.

and you solve it like a quadratic equation:

so basically:

y= is either 2,1

thus x= 100, or 10 and log(x)= 2, or 1

Thanks to both for the quick replies.
